Description

Technical Field

[0001] This utility model relates to the field of tooling and fixtures, specifically to a riveting fixture for a circuit breaker lever. Background Technology

[0002] like Figure 1 The circuit breaker lever 1 shown includes a pair of side plates 11 and multiple connecting posts 12. Each connecting post 12 is riveted between the two side plates 11. A rod hole 13 is opened in the middle of the side plate 11. The rod hole 13 is a hexagonal hole for the rotating rod to pass through. During the riveting process, a riveting clamp is required for the lever 1. The clamp is used to constrain the side plates and connecting posts, so that the riveting machine can rivet stably.

[0003] See previous fixtures Figure 1 As shown, the fixture includes a clamp 2 and a pad 52. The clamp 2 has an installation groove. After the lever 1 is assembled, it is first placed in the installation groove, and then the pad 52 is placed between the two side plates 11. The clamp is then pressed together by a riveting machine. The previous drawbacks of this type of fixture are: First, during the riveting process of the connecting column, the two side plates will experience slight positional displacement, resulting in a misalignment of the rod holes on the two side plates, meaning the rod holes are not in the same axial direction, affecting the subsequent insertion of the rotating rod; Second, after the lever is riveted, the pad is clamped between the two side plates, making it difficult to remove manually.

[0004] In summary, traditional lever riveting fixtures affect the riveting quality and efficiency of the lever. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] This application provides a riveting clamp for a circuit breaker lever, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0047] To address the problem that existing riveting clamps affect the riveting quality and efficiency of circuit breaker levers, this application provides a riveting clamp for circuit breaker levers in one embodiment. This is described in detail below.

[0048] like Figures 2 to 6 As shown, a rivet clamp for a circuit breaker lever includes...

[0049] The clamp 2 has at least one riveting position on its platform, and the lever 1 to be riveted is adapted to be placed flat on the riveting position.

[0050] Positioning mechanism 3, which is adapted to pass through the two rod holes 13 of lever 1 to restrict the translation of lever 1 at the riveting position;

[0051] The pad block mechanism 5 rotates horizontally and is adapted to be inserted between the two side plates 11 of the lever 1 to limit the riveting and shaping spacing of the two side plates 11.

[0052] The clamping mechanism 4 is adapted to vertically clamp the lever 1 on the riveting position.

[0053] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the clamp 2 includes a top plate, multiple vertical plates and a bottom plate. Each vertical plate is located between the top plate and the bottom plate, and the top plate is supported by the vertical plates. The riveting position is located on the top plate.

[0054] In this embodiment, the number of riveting positions can be one or two. When there are two riveting positions, the left riveting position is responsible for riveting the front of lever 1, and the right riveting position is responsible for riveting the back of lever 1. The dual-position structure can improve the riveting efficiency of lever 1.

[0055] Specifically, as an optional implementation method in this embodiment, such as Figure 3As shown, the positioning mechanism 3 includes

[0056] The first cylinder 31 is fixedly mounted on the clamp 2;

[0057] The positioning mandrel 32 extends from the top plate of the clamp 2 at its upper end and is connected to the first cylinder 31 at its lower end. The first cylinder 31 drives the positioning mandrel 32 to move up and down.

[0058] Specifically, the first cylinder 31 is suspended below the top plate of the clamp 2. When the positioning mandrel 32 needs to position the lever 1, the first cylinder 31 drives the positioning mandrel 32 to rise upward. After the lever 1 is riveted, the positioning mandrel 32 retracts downward.

[0059] In this embodiment, the cross-section of the positioning mandrel 32 can be circular. The positioning mandrel 32 is responsible for limiting the translation of the lever 1 at the riveting position. The actual horizontal position of the lever 1 can be controlled by other limiting components at the riveting position.

[0060] Specifically, as an optional implementation method in this embodiment, such as Figure 3 As shown, the positioning mandrel 32 has a polygonal cross-section and is adapted to the shape of the rod hole 13. The positioning mandrel 32 is inserted into the rod holes 13 of the two side plates 11 to restrict the two side plates 11 from rotating horizontally.

[0061] In this embodiment, the rod hole 13 has a hexagonal structure, and the positioning mandrel 32 also has a hexagonal cross-section. After the positioning mandrel 32 is inserted into the rod hole 13, the two side plates 11 cannot be misaligned and rotated horizontally on the positioning mandrel 32, so that the two side plates 11 of the lever 1 are always in the same position, ensuring the riveting quality of the lever 1.

[0062] Specifically, as an optional implementation method in this embodiment, such as Figure 5 As shown, the clamping mechanism 4 includes

[0063] The second cylinder 41 is fixedly mounted on the clamp 2;

[0064] Pressure plate 42, one end of which is connected to the second cylinder 41, and the other end of which is adapted to press the lever 1.

[0065] Specifically, when there are two riveting positions, the clamping mechanism 4 is located between the two riveting positions, and the middle part of the pressure plate 42 is connected to the push rod of the second cylinder 41 through a pin.

[0066] Specifically, as an optional implementation method in this embodiment, such as Figure 2 and Figure 5As shown, the pressure plate 42 has a guide hole, and the clamp 2 is provided with a guide rod 44. The guide rod 44 passes through the guide hole to guide the pressure plate 42 to move up and down.

[0067] There are two pairs of guide rods 44, located on both sides of the second cylinder 41. In addition to guiding the pressure plate 42 to move up and down, the two pairs of guide rods 44 can also prevent the pressure plate 42 from rotating.

[0068] Specifically, as an optional implementation method in this embodiment, such as Figure 2 , Figure 5 as well as Figure 7 As shown, a pressure head 43 is provided at the end of the pressure plate 42. An avoidance hole 431 is provided at the lower end of the pressure head 43. When the pressure head 43 presses the upper side plate 11 of the lever 1, the avoidance hole 431 corresponds to the rod hole 13 of the side plate 11.

[0069] In this embodiment, the pressure head 43 is made of rubber, and the upper end of the pressure head 43 is connected to the pressure plate 42 by a pin.

[0070] like Figure 7 As shown, the clearance hole 431 is located in the middle of the lower part of the pressure head 43 and is directly above the positioning mandrel 32. After the positioning mandrel 32 passes through the lever 1, the upper end of the positioning mandrel 32 is inserted into the clearance hole 431, so that the pressure head 43 can fully press the lever 1.

[0071] Specifically, as an optional implementation method in this embodiment, such as Figure 2 and Figure 4 As shown, the pad mechanism 5 includes

[0072] The pad 52 includes a connecting part 521 and at least one pad holding part 522. The connecting part 521 forms a horizontal rotational engagement with the clamp 2, and the pad holding part 522 is adapted to be inserted between the two side plates 11 of the lever 1.

[0073] The third cylinder 51 is horizontally positioned on the clamp 2 and is connected to the pad 52 to drive the pad 52 to rotate horizontally.

[0074] like Figure 4 As shown, the push rod of the third cylinder 51 is connected to the pad 52 via a pin. The rear end of the third cylinder 51 is connected to the clamp via a cylinder seat 53. Specifically, the cylinder seat 53 has an L-shaped structure. The rear end of the third cylinder 51 is fixed on the cylinder seat 53. The cylinder seat 53 rotates with the clamp via a rotating shaft. A bearing is provided between the rotating shaft and the cylinder seat 53 to reduce the resistance to the rotation of the cylinder seat 53. When the third cylinder 51 drives the pad 52 to rotate, the third cylinder 51 can rotate horizontally on the clamp, thereby driving the pad 52 to rotate.

[0075] The number of pad holding parts 522 is determined according to the riveting position. When there are two riveting positions, both ends of the pad block 52 are pad holding parts 522, and the connecting part 521 is located in the middle of the pad block 52. The connecting part 521 forms a shaft hole in the pad block 52, and rotates with the clamp 2 through the shaft hole so that the pad block 52 can rotate horizontally around the clamp 2.

[0076] Specifically, the padding part 522 is responsible for inserting between the two side plates 11 of the lever 1. The distance between the padding part 522 and the side plates 11 is controlled at about 10 microns. The distance between the two side plates 11 of the lever 1 is controlled by controlling the thickness of the padding part 522.

[0077] As lever 1 is riveted, the upper side plate 11 is pressed downward. After lever 1 is riveted, the pad 522 is actually clamped between the two side plates 11. At this time, it would be very difficult to remove the pad 52 manually. Now, by rotating the pad 52 with the third cylinder 51, the pad 52 can be easily moved out from between the side plates 11.

[0078] Specifically, as an optional implementation method in this embodiment, such as Figure 4 As shown, a notch 523 is provided on the padding part 522, which is used to cooperate with the positioning core rod 32 inside the lever 1, so that the padding part 522 can be fully inserted into the lever 1.

[0079] Specifically, as an optional implementation method in this embodiment, such as Figure 5 and Figure 6 As shown, a cylinder guide sleeve 61 is provided on the clamp 2, and the connecting part 521 is sleeved on the outside of the cylinder guide sleeve 61 and rotates with the cylinder guide sleeve 61.

[0080] The push rod of the second cylinder 41 of the clamping mechanism 4 extends out from the cylinder guide sleeve 61.

[0081] In this embodiment, as Figure 6 As shown, the cylinder guide sleeve 61 includes a cylinder body and a flange. The cylinder guide sleeve 61 is installed on the top plate of the clamp 2 through the flange. The connecting part 521 of the pad 52 is sleeved on the cylinder body of the cylinder guide sleeve 61. The outer part of the cylinder body is sleeved with a copper sleeve 62. The pad 52 rotates with the cylinder guide sleeve 61 through the copper sleeve 62.

[0082] Specifically, as an optional implementation method in this embodiment, such as Figure 5 As shown, a foolproof block 71 and a limiting rod 72 are provided on the table surface on one side of the riveting position.

[0083] The foolproof block 71 is used to prevent the operator from mistakenly operating the lever 1 at the riveting position, that is, the operator places the lever 1 in the reverse direction at the riveting position when it should be placed upright.

[0084] The limiting rod 72 is used to precisely position the lever 1 at the riveting position.

[0085] The positions of the anti-fool block 71 and each limit rod 72 are determined by the operator based on the actual size of the lever 1.

[0086] The working process of the riveting clamp for the circuit breaker lever of this utility model:

[0087] First, assemble lever 1. Then, according to the limiting rod 72 on the riveting position, install lever 1 in the riveting position. Next, raise the positioning mandrel 32 and insert it into the rod holes 13 of the two side plates 11 of lever 1. Then, control the pad block 52 to rotate, insert the pad holding part 522 horizontally into lever 1, so that the pad holding part 522 can be between the two side plates 11. Then, control the pressure plate 42 to move down, and press the lever 1 tightly through the pressure head 43. After the lever 1 is pressed tightly, the riveting machine can rivet the various connecting posts 12 on lever 1. After riveting is completed, the pressure plate 42 is raised, and the pad 52 is rotated in the opposite direction to make the pad holding part 522 leave the lever 1. Finally, the positioning mandrel 32 is retracted. At this time, the lever 1 on the left riveting position can be removed. The lever 1 is then removed and placed directly on the right riveting position for riveting on the other side. Meanwhile, the left riveting position continues to install the next lever 1 to be riveted. This process is repeated, which greatly improves the riveting efficiency of the lever 1 and ensures the riveting quality of the lever 1.
